It sounds to me like you made a (relatively) good decision. You’re buying a house because you want a place to live. You’re also buying to address other concerns you have, such as space and customization. I think as long as it makes you happier and you can afford it, don’t worry about if the value goes down a bit. It will eventually come back up. In the meantime, you’ll be in a place that makes you happy. And that’s what really matters.
I think what you find on this blog are people (myself included) who were priced out of the market and cannot afford a place if they wanted to. The fact that you can comfortably pay the monthly payment puts you in a whole different category. Unfortunately, I need to wait a while longer before this even becomes an option for me.
